Bursty Precipitation of Relativistic Electrons Unveiled by CIRBE/REPTile‐2 Measurements and Their Physical Implications

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Energetic electron precipitation plays a pivotal role in shaping Earth's radiation belt dynamics and drives significant physical and chemical changes in the upper atmosphere. However, the detailed mechanisms governing the loss of relativistic electrons have remained unclear, largely due to the limited energy coverage and coarse resolution of ...

On the Possibility of Driving the Electron Flux Probabilistic Models by the AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We present the new probabilistic model of the electron fluxes designed to assess the risks of the spacecraft surface charging for missions with near‐equatorial orbits in the inner magnetosphere. It is a second model developed within a frame of the European Space Agency's activity “Plasma Environment Modeling in the Earth's Magnetosphere ...

Switchable Reactivities of Metalated Phosphasilenes Regulated by Reversible 1,2‐Metal Migration

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
We develop novel strategies for the facile synthesis of anionic phosphasilenes in the forms of both P‐metalation and Si‐metalation. The P‐metalated phosphasilene displays a pronounced π‐bond‐driven reactivity toward robust inert molecules, whereas the Si‐metalated analogue behaves as a silylene equivalent via a retro‐1,2‐silver migration.

Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe ${f}_{pe}$/fce ${f}_{ce}$

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Whistler‐mode chorus waves play a key role in driving radiation belt dynamics by enabling both acceleration of electrons to relativistic energies as well as their loss into the atmosphere via pitch‐angle scattering. The ratio between the electron plasma frequency (fpe ${f}_{pe}$) and the electron gyrofrequency (fce ${f}_{ce}$) significantly ...

Single‐source precursor synthesis of a compositionally complex early transitional metal nitride (V, Nb, Ta, Mo, W)Nx and its high temperature stability

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Compositionally complex transitional metal nitrides are an interesting class of ceramics with superior chemical, thermal, and mechanical stability, with a high potential in ultra‐high temperature applications and catalysis. The exceptionality in the properties may partly be explained as a consequence of their high configuration entropy ...

Twisted Tin‐Chloride Perovskite Single‐Crystal Heterostructures

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Replacing lead with tin in a single‐crystal halide perovskite heterostructure drives a twist between the perovskite (gray) and intergrowth (blue) layers. The accompanying structural distortions and interfacial strain change the calculated orbital composition of the band edges and enable high in‐plane optical anisotropy in the Sn analog.
